Bioequivalence and Bioavailability Forum

Dear Libaiyi,

❝ Now I met a study design and analysis method problem. I had PK data from US. And now this drug needs to be put into other regions such as Asia. So we setup a new study, it is a single arm trial. How can I compare the PK data from the new trial to historical US PK data?

Like Helmut I also never came across such a design during my active working period.

But eventually your problem is something like "Bridging study".
